Temperature Question!!

I was wondering if someone could tell me if your body temperature stays high on DPO10 is there a chance i've conceived?  i'm not sure how the BBT works exactly.  My face feels hotter than the rest of my body which is unusual i'm not tracking my temp but just wondered if your body heat gets lower or higher if you think you have conceived

I read on one site if you have an elevated temp for eighteen days or more that you're pregnant. Keep checking, and BABY DUST!!!

thank you, i'm not feeling to good today, my sore head won't go away and i feel so tired i also had a bit of a dodgy stomach again.  Hope you get your BFP as well this month!!

Your temp goes up as soon as you ovulate and will stay high until your period. I have looked at many charts and the majority of women's temps go down on the day they start AF. A rare few go down the day after AF or the day before AF.
